Dry, flaky skin
Dry, flaky skin may affect people with low levels of iodine. According to studies, nearly 77% of people with low thyroid hormone levels experience dry skin. Thyroid hormones contain high levels of iodine that facilitate skin regeneration. When thyroid hormone levels are low, your skin loses its ability to regenerate. This will eventually lead to flaky, dry skin. These hormones also help regulate body sweat. People with low levels of thyroid hormone [5], like iodine deficiency, tend to sweat less than people with normal levels of thyroid hormone. Since sweat helps keep the skin moist and hydrated, the inability to produce sweat may also be responsible for the fry, flaky skin.
